NOTE:
•
The media dependent port (MDI) standard is typically used on the Ethernet port of network adapters.
The media dependent port crossover (MDI-X) standard is typically used on hubs or LAN switches.
•
When 10/100 Mbps and half duplex/full duplex are specified for a copper Ethernet port, the copper
Ethernet port operates in the forced mode. When 1000 Mbps is specified or the rate and the duplex
mode are not simultaneously specified for a copper Ethernet port, the copper Ethernet port operates in
the auto-negotiation mode.
•
A copper Ethernet port supports automatic MDI/MDI-X in both the forced mode and the
auto-negotiation mode; namely, it supports both straight-through and crossover cables.

Port lightning arrester (optional)
Before connecting an outdoor Ethernet cable to an Ethernet port, you can install a port lightning arrester
to protect the router against lightning strikes.
The following port lightning arrester can be installed on the SR6602. The specifications for the port
lightning arrester are as follows:
